Written records show that honey was used to treat infected wounds more than 2,000 years before it was known that bacteria caused infections.
Honey produced by the honey bee (Apis mellifera) is one of the oldest traditional medicines for a number of human ailments and it can even be effective on antibiotic-resistant strains of bacteria.
The antimicrobial activity in most honeys (that has not been heat treated) is due to an enzyme Glucose Oxidase that catalyses glucose to form hydrogen peroxide. Certain types of nectar like manuka also have antibacterial properties that can act in addition to the hydrogen peroxide or on its own.
The purpose of the black and white stripes on zebra has been the subject of some speculation. One suggestion is that stripes make it difficult for predators to single out an individual zebra from the herd, but experimental evidence to support that and other ideas has been lacking.
Turns out bloodsucking horseflies and tsetse flies who do not only deliver nasty bites but also carry dangerous germs find zebra stripes less attractive than uniform colouration.
The Addo Elephant Park’s flightless dung beetle (Circellium bacchus) has no wings, but uses the sealed wing case as a CO2 store to exhale less frequently and thus minimize moisture loss during breathing.
This allows the beetle to survive the arid conditions prevalent in that part of the Eastern Cape.
And yes, in Addo dung beetles have right of way.
Stillsuit is a moisture saving suit from the book Dune (by Frank Herbert).
